Cronbach's alpha

Cronbach's Alpha is a statistic used to measure the reliability, or consistency, of a set of questions or items intended to assess a particular concept, like general knowledge. If you have a quiz with multiple questions on general knowledge, Cronbach's Alpha helps determine if the questions are yielding similar results. A higher value (closer to 1) indicates that the questions are well-aligned and consistently measure the same thing, while a lower value suggests inconsistency. This tool helps researchers and educators ensure that their assessments accurately reflect what they intend to measure.
